Be it known that I, LOUIS P. HAGER, of and thus cause the heated air and products Waltham,in thecountyofMiddleseX and State of combustion to pass out at the sides. of Massachusetts, have invented certain new Like letters of reference refer to like parts 5 and useful Improvements in Apparatus for throughout the several views.

Heating'and Agitating Air, of which the fol- In Eig. 1, B represents an ordinary Argand lowing is a specification. gas-burner with the usual chimney B, around My invention relates to improvements in which is located the shade B and resting apparatus for heating and diffusing a body of upon the upper edge of said shade is a metal-- :0 air throughout an apartment to be heated. lic chimney B of greater diameter than the In carrying out my invention I locate a hood chimney B, and across the upper part of said above the upper end of a chimney and revolve chimney is a diametrical supporting-rod B. the same by the ascending current of heated B represents a supporting-arch, and in the air and products of combustion ascending upper portion of the same is journaled the I5 through said chimney from a source of heat rod B the lower end of which, B rests and which is also used for heating the air of the turns in the supporting-rod B and B repreapartment, so that in my apparatus-one source sents a revolving hood composed of a numof heat acts as a motive power to revolve the her of separated curved floats B secured to hood which receives the heated air and prodthe rod B and turning therewith. The floats 2o nets of combustion and also heats the air of are in contact at their upper ends, thus makthe apartment. ing a closed top for the hood, and are sepa By my invention the heated air and prodrated from each other at the sides of the hood nets of combustion from a source of heat are to form lateral openings, through which the intercepted as they are discharged from the heated air and products of combustion pass,- 25 top of the chimney and diflused throughout owing to the top being closed, and in their the apartment to be heated by the revolving discharge act on the floats, which are placed hood, thereby producing an equable temperat an angle to the line of discharge of the ature instead of allowing the heated air and heated air and products of combustion and products of combustion to ascend to the ceilcause the revolution of said hood, and said 0 ing, as is the case with ordinary radiators, lateral discharge facilitates the diffusion of which heat by natural convection. the heated air and products of combustion My invention consists of certain novel feain a horizontal direction. Located within tures hereinafter described, and particularly said revolving hood and at about the center pointed out in the claims. thereof is a diaphragm B supported in a 35 In the accompanying drawings,which illushorizontal plane at its center by the vertitratea construction embodying my invention, cal rod B and the object of this diaphragm Figure l is a side view of an ordinary Argand is to arrest the upward current of heated gas-burner with the revolving hood above the air and products of combustion and deflect upperend of the chimney to receive the heated thesame in a horizontal direction, thereby 40 air and products of combustion to prevent causing them to come in contact with the their ascending to the ceiling and adapted to floats at their center, where the pitch is best diffuse the same throughout the apartment adapted for motion. The metal chimney 13 upon the revolution of said receiving-hood, has a number of perforations, and located 7 Fig. 2 is a detail side view in section of the around said chimney is a ring B having a 45 hollow revolving hood into which the heated corresponding number of perforations, which air and products of combustion ascend. Fig. are adapted to register with the perforations 5 3 is a plan view of the revolving hood, showon said chimney B and upon the movement ing the floats separated at the sides of the of said ring over said perforations the draft hood to form lateral openings and in contact of ascending air may be regulated.

The heated air and products of combustion passing from the chimney into the revolving hood 13 heat the same, so that the surrounding air of the apartment is heated by coming in contact with the outer heated surface of the revolving hood and is thrown off and diffused throughout the apartment, so that in this apparatus the revolving hood not only arrests the upward current of heated air and products of combustion, diifusing them throughout the apartment, but also heats the external air by direct contact with its heated surface and diffuses the same. i

The heated air and products of combustion passing outwardly between the floats are thrown at a tangent from the hood and are dilfused throughout the apartment to be beated, so that the hood is revolved and the apartment is heated by the said current of air. The heated air and products of combustion discharge laterally from said hood, causing the hood to revolve by impact on the floats, and said discharge is accelerated by the revolution of said hood, owing to centrifugal force.

The object of regulating the draft by the metallic ring 13 is to vary the speed of the revolving hood B and thereby regulate the temperature of the room without disturbing the [lame of the burner which may at the time be in use for illuminating purposes. \Vhen the draft is open, the air flows in more freely, thereby accelerating the speed of the revolving hood, and when the draft is partially or entirely closed the speed of the revolving hood is lessened and the difiusion of the heated air and products of combustion becomes less perfoot and part of the heated air and products of combustion goes to the ceiling and the lower part of the room becomes cooler,

I do not limit myself to the arrangement and construction shown, as the same may be varied without departing from the spirit of my invention.

Having thus ascertained the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In an apparatus of the character specified, a source of heat for heating the airby direct contact, a support, and a hood closed at the top and open at the sides and pivoted on said support and consisting of a number of floats separated from each other at the sides to form lateral openings and located at an angle tothe line of passage of the heated air and products of combustion and adapted to receive and intercept the heated air and products of combustion and to be revolved by the lateral discharge of the same against said floats in passing through said openings and adapted by its revolution to accelerate the difiusion of the heated air and products of combustion throughout the apartment to be heated.

2. In an apparatus of the character specified, a source of heat for heating the air, a revolving hood for receiving the heated air and products of combustion and revolved thereby and adapted in its revolution to discharge and diffuse said heated air and products of combustion throughout the apartment to be heated, and means for controlling the speed of said hood by regulating the admission of air.

3. In an apparatus of the character specified, a source of heat for heating the air, a revolving hood for receiving the heated airand products of combustion and revolved thereby and adapted in its revolution to discharge and difliuse said heated air and products of combustion throughout the apartment to be heated, and means for deflecting the heated air and products of combustion from their upward course.

4. In an apparatus of the character specified, a source of heat for heating the air, a revolving hood for receiving the heated air and products of combustion and revolved thereby and adapted in its revolution to discharge and difiuse said heated air and products of combustion throughout the apartment to be heated, and a diaphragm located within said hood for deflecting the heated air and products of combustion from their upward course.

5. In an apparatus of the character specified, a source of heat for heating the air by direct contact, a support, and a hood closed at the top and open at the sides and pivoted on said support and consisting of a number of curved floats in contact at their upper ends and separated from each other at the sides to form lateral openings and located at an angle to the line of passage of the heated air and products of combustion and adapted to rc ceive and intercept the heated air and products of combustion and to be revolved by the lateral discharge of the same against said floats in passing through said openings and adapted by its revolution to accelerate the diifusion of the heated air and products of combustion throughout the apartment to be heated.

In testimony whereof I have signed my name to this specification, in the presence oftwo subscribing witnesses, this 6th day of August, A. D. 1898.
